The in-game coin system provides an extra dimension to Drift Boss, giving players something tangible to strive for during each run. Coins can be collected while driving or earned as part of daily bonuses. These coins are then used to unlock new cars and upgrades, creating a progression loop that adds more depth to the simple mechanics. This feature cleverly balances instant fun with long-term goals. Players feel motivated not just to survive longer but also to collect as many coins as possible, turning each run into an opportunity for growth and excitement.
